عَنْ أَبِي نَضْرَةَ عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ لَا يَمْنَعَنَّ أَحَدَكُمْ هَيْبَةُ النَّاسِ أَنْ يَقُولَ فِي حَقٍّ وَفِي لَفْظٍ أَنْ يَتَكَلَّمَ بِالْحَقِّ إِذَا رَآهُ أَوْ شَهِدَهُ أَوْ سَمِعَهُ قَالَ أَبُو سَعِيدٍ وَدِدْتُ أَنِّي لَمْ أَسْمَعْهُ
It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: When a person sees the truth, or is present upon it, or hears it, then the awe of people should not prevent him from stating the truth. Abu Sa'id said: I wish I had not heard this hadith.
